本文通过对中条山地区表土花粉的百分比图谱分析和几何平均法线性回归分析认为：表土花粉谱基本上反映了当地植被的基本特征，但不能准确反映植物在植被中的数量关系。几何平均法回归分析是研究植物和花粉数量关系的一个切实可行的方法。并对影响回归分析结果的几种主要因素进行了讨论。

In this paper, the author deals with the relationship between tree and pollen in Zhongtiao Mountain by surface pollen analysis.The author, applying the methods of the analysis of surface pollen diagram and the regres-sion analysis by using the geometric-mean, makes out that sufface diagram in Zhongtiao Moun-tain can reflect the feature of vegetation. The author also comments that it is feasible to studythe relationship between tree and pollen by the regression of the geometric-mean, and discussthe main factors affecting the results of regression analysis.
